Tax deductions every small business should know

Are you claiming what you are entitled to?

Tax deductions can reduce taxable income, but they must be legitimate, supported by records and connected to the business. The goal is not to claim aggressively. The goal is to claim correctly, consistently and confidently.

The core principle of deductions

A deduction generally needs to relate to earning business income and be supported by evidence. If an expense has both business and private use, only the business portion should be claimed. This is why clear records, business-purpose notes and consistent coding matter. Without those records, business owners may either miss deductions or claim amounts that are difficult to support.

Common categories to review

Common small business deductions may include accounting and professional fees, software subscriptions, business insurance, office supplies, marketing and advertising, internet and phone costs, staff training, bank fees, motor vehicle costs, equipment, repairs, and home office expenses where applicable. Each category should be reviewed based on the business facts. For example, vehicle expenses may require logbooks or other substantiation depending on the method used. Home office and phone expenses may require reasonable apportionment between private and business use.

Deductions must be supported by records

The ATO focuses heavily on record keeping because deductions and GST credits need evidence. A business should keep invoices, receipts, bank statements, contracts and documents that show the business purpose of a transaction. Where the business uses digital records, those records should be clear, readable and accessible when needed. This makes year-end tax preparation faster and reduces the chance of missing legitimate claims.

Avoiding risky deduction behaviour

Some deductions create risk when they are estimated without support, mixed with personal expenses, coded inconsistently or claimed in the wrong period. Overclaiming can lead to ATO review, penalties, interest and professional rework. Underclaiming, on the other hand, means the business may pay more tax than necessary. A professional review helps balance tax efficiency with compliance.
